Abundance of entire solutions to nonlinear elliptic equations by the variational method

Analysis of PDEs 2018-11-09 v1

Abstract

We study entire bounded solutions to the equation Δuu+u3=0\Delta u - u + u^3 = 0 in R2\mathbb R^2. Our approach is purely variational and is based on concentration arguments and symmetry considerations. This method allows us to construct in a unified way several types of solutions with various symmetries (radial, breather type, rectangular, triangular, hexagonal, etc.), both positive and sign-changing. The method is also applicable for more general equations in any dimension.
